In Spanish slang, 'pulmón' literally translates to 'lung'. However, it is often used metaphorically to describe a person who is very hardworking or the main source of income in a family or organization.
Examples
- Spanish: Mi madre es el pulmón de nuestra familia, siempre trabajando para que no nos falte nada.
- English: My mother is the 'lung' of our family, always working so we don't lack anything.
